AI Technical Summary

Problems solved by technology

However, amphiphilic amide lipids have a high melting point and are prone to crystallization, so they cannot be added in a sufficient amount, and there is a problem that they are almost completely washed off in rinse-off hair cosmetics, making it difficult to obtain sufficient effects.

Embodiment 1～5 and comparative example 1～3

[0087] The hair care conditioners shown in Table 1 were prepared and evaluated.

[0088] (Production method)

[0089] (1) Put the ingredients other than purified water and methyl paraben into a 500ml beaker according to the final production volume of 400g, heat to 90°C, and stir with a three-wing homogenizer at 250rpm.

[0090] (2) Purified water was heated to dissolve methylparaben, and then, the mixture obtained in step (1) was added and emulsified. Furthermore, the melting point of docosanol was measured with a differential scanning calorimeter (manufactured by SEIKO, SSC5200 series, DSC120, heating rate 1° C. / min), and 1.5 wt. % and docosanol 5% by weight in the gel phase transition temperature of the composition emulsified in water. As a result, the melting point of docosanol was about 72°C, and the phase transition temperature was about 85°C. Therefore, the emulsification temperature was set at about 75°C.

Abstract

Provided are a preparation process for a hair cosmetic composition having the step of emulsifying an aqueous composition having (A) an amphipathic amide lipid, (B) a quaternary ammonium salt (b-1) or tertiary amine type compound (B-2) or salt thereof, and (C) a higher alcohol (c): R''-OH (c) (wherein, R and R'' represents C12-28 aliphatic hydrocarbon, R' represents C1-3 alkyl, X<-> represents anion, A represents H or amide group having 12 to 24 carbon atoms in total, N-(hydrocarbon carbamoyl), acyloxy or hydrocarbon oxy, B represents C1-22 divalent hydrocarbon, and Y<1 >and Y<2 >represents C1-4 alkyl) at a temperature equal to or greater than the melting point of Component (C) but less than the phase transition temperature of a composition composed of Components (B) and (C), each in an amount equal to the content of the intended hair cosmetic composition, and balance water; and a hair cosmetic composition thus obtained. The hair cosmetic composition obtained by the process described above provides benefits such as excellent lubrication and flexibility to the hair during from application to washing-away (rinsing), provides resilience, body and effect-remaining feel for the hair after drying and at the same time, has excellent effects for preventing hair damage and has excellent emulsion stability.

Description

technical field [0001] The present invention relates to a method for producing a hair cosmetic that imparts a good feel to hair and prevents hair damage. Background technique [0002] After shampooing, hair cosmetics such as conditioners, conditioners, and combing agents are often used to prevent hair from tangling and to improve the feeling. Cationic surfactants and higher alcohols are added to these hair cosmetics, but their effects are not satisfactory for improving softness, moisturization, and the like. In addition, in recent years, the number of consumers who are frequently subjected to chemical stimulation caused by perm, hair dyeing, bleaching, etc. has increased, and the hair is in a state of severe damage accompanied by partial defects in the internal components and structure of the hair. Such problems as dryness during washing of hair, protection and restoration of hair cannot be sufficiently solved by existing hair cosmetics. [0003] As methods for improving t...
